Patent DE-19735433-A1 (DE)
Title: Measuring probe for measuring thin layers e.g. paint, varnish, galvanised layer
Inventor: NIX HANS FRIEDRICH DIPL ING
IPC: G01D11/24
Filed: 1997-08-15
Abstract: The measuring probe has a stop (9) at the guide unit (3) working with an abutment (9a) at the probe housing (5), and a push element (2) provided above the abutment for a measuring sensor (12), is guide movable limited by a stop at the probe housing. Two coil springs (4, 10) of different spring force, working together with each other, are arranged between the push element and the measuring sensor in the force path. The different spring forces are so measured, that in the starting position of the measuring sensor, the spring force of one of the coil springs (4) is less than the spring force of the other spring (10). Such that with the operation of the push element, first the coil spring (4) is loaded so much, until its spring force overpowers the counter force of the other spring, so that guide unit (3) is moved with the measuring sensor only against the working of the other spring from the drawn back rest condition into the measuring position. After reaching this, further pressure on push element is elastically absorbed by first coil spring.

Title: Surface cooling system
IPC: H04R9/02
Filed: 1997-10-14
Abstract: The cooling system has radial cooling surfaces on the loud speaker driving permanent magnets. The cooling surfaces are attached to a circular surface and are connected to the magnets by aluminum surfaces attached to an aluminum carrier. The carrier is round and at least 10 mm. It has a gap at some point in its circular surface. The carrier has two extensions at the gap which are bent upwards at 90 deg. The bent parts have holes through which fastening screws pass. The aluminum cooling surfaces are in a vertical parallelogram shape. The cooling surfaces are as wide as the carrier. Alternatively, they are up to 150 per cent wider, flat at the front and upright at the back. The height of the cooling surfaces is at most 90 per cent of the total diameter. The number of cooling wings depends on the angle of the carrier. The cooling surfaces are flat or bent according to their length and desired stability.

Patent DE-19758111-A1 (DE)
Inventor: SCHULZ GUNTHER DR
IPC: B22F9/08
Filed: 1997-12-17
Abstract: The invention relates to a method for producing fine powder preferably having a spherical habit by atomizing molten materials with gases. In order to economically manufacture fine, gas atomized powder in addition to avoiding standstill times caused by clogging due to impure molten materials and by freezing due to heat loss, the invention provides that the molten material (5) flows out of a molten material nozzle (4) with an essentially rectangular outflow cross-section (8) in the form of a film (6). Afterwards, the molten material, together with an atomizing gas, flows out of a linear Laval nozzle (3) through a firstly converging and then diverging gas nozzle (3) having an essentially rectangular cross-section, whereby the laminar accelerated gas flow stabilizes and simultaneously draws the molten film (6) in a converged part of the Laval nozzle (3) until the molten film (6) is evenly atomized over an entire length after passing through the narrowest cross-section (9).

Title: Verfahren und Anordnung zur Abwehr kryptoanalytischer Untersuchungen
Inventor: PHILIPP STEFAN
IPC: H04L9/30
Filed: 1998-03-14
Abstract: Kryptoanalytische Anorndungen werden benutzt, um Nachrichten oder Daten nur einem berechtigen Personenkreis zugänglich zu machen. Dabei werden Verfahren genutzt, die mit geheimen und öffentlichen Schlüsseln arbeiten. Da der benutzte Schlüssel immer dasselbe Bitmuster aufweist, kann mit einem äquivaltenten Aufbau der Anordnung und entsprechend vielen Zeitmessungen der Schlüssel von Unberechtigten bitweise analysiert werden. Um diese Art der Analyse prinzipiell zu umgehen, wird der Schlüssel, der in diesem Verfahren Exponent ist, mit einem Bitmuster verknüpft. Dadurch variiert das Bitmuster, mit dem die Nachricht verschlüsselt wird, bei jeder Berechnung und der Aufbau der kryptoanalytischen Anordnung läßt sich somit nicht nachvollziehen. Damit ist die Ermittlung der geheimen Schlüssel für kryptoanalytische Untersuchungen wesentlich erschwert.

Abstract: The invention relates to a method for regulating a NOx absorption catalytic converter of an internal combustion engine, comprising a NOx-sensitive measuring device which is positioned downstream of the catalytic converter in the direction of exhaust-gas flow and a control unit. According to said method the NOx-sensitive measuring device determines the NOx concentration of the exhaust gas, the quantity of NOx stored in the catalyst during lean-mixture operations is integrated by means of the NOx concentration signal and lean-mixture operation of the internal combustion engine is terminated when the NOx quantity stored reaches a defined limit value. The invention also relates to a method for regulating a NOx absorption catalytic converter of an internal combustion engine permitting at least temporary lean-mixture operations. According to said method lean-mixture operation is triggered in accordance with catalytic converter temperature, in that lean-mixture operation is terminated when the temperature of the catalytic converter is lower than a defined minimum temperature or higher than defined maximum temperature. The minimum and maximum catalytic converter temperature is modified in accordance with the duration of the lean-mixture or regeneration intervals so as to permit optimal use of the NOx absorption capacity.
